Description
The CN9, CN10, CN14, and CN15 headers complement to give access to all GPIOs of the STM32U575AII6Q
microcontroller. In addition to GPIOs, the following signals and power supply lines are also routed on these
connectors:
•
GND
•
5V
•
3V3
•
5V_DC
•
VDD
•
RESETn
•
Clock terminals PC14-OSC32_IN, PC15-OSC32_OUT, PH0-OSC_IN, and PH1-OSC_OUT
CN9 and CN10 are two
‑
row headers of 25 pins, with a 1.27 mm pitch.
CN14 and CN15 are two
‑
row headers of 17 pins, with a 1.27 mm pitch, mainly used for FMC interface access.
